Abstract

In this present study, an attempt has been made to determine the uncertainty occurring in pushover analysis results for a Reinforced Concrete (RC) G+2 storied frame modeled as a bare frame and frame with rigid diaphragm slab by considering userdefined hinges using non-linear static pushover analysis using SAP2000. Since the output of the analysis is very much sensitive and susceptible to design parameters, to interpret the sensitivity analysis by varying the strength of steel, concrete and hinge lengthon the performance of structures and compare the variation in the performance which is randomly generated and incorporated into the analysis. The nonlinear behavior of the elements wasmodeled using plastic hinges based on the momentcurvature relationship as described in Federal Emergency Management Agency (FEMA)-356 and Applied Technology Council (ATC)-40. A seismic response like base shear, roof displacement corresponding to performance point was evaluated using nonlinear static analysis. The experimental results were compared with analytical results.
